IMPROVEMENT IN AIR-MOISTENING APPARATUS.

Specilication forming part of Letters -Patent No. l 88,063, dated March6, 1877; application filed February 6, [877.

To all whom it may concern.-

Be it known that I, CHESTER R..MEER1LL, of Boston, ofthe county ofSuffolk and State of Massachusetts, have invented a new and usefulApparatus for Moistenin g or Odorizing the Air of an Apartment; and dohereby declare the same to be described in the following specificationand represented in the accompanying drawings, of which- Figure l is avertical section of the said apparatus under one construction of it.Fig. 2 is a similar section under a somewhat 4varied construction. I

It, as shown, is designed to be fixed to a radiator, such as generallyused for heating anapartment by steam let into `such radiator.

In the drawings, A is a foraminous vessel, cylindrical Ain shape, andarranged concentrically within a case, B, open at its upper end. Thevessel A is encompassed by a .cloth jacket, C. From the bottom of thecase B a pipe, D, provided with a stop-cock, E, is extended, such pipeopening through such bottom, and directly into the foraminons vessel A,or into a chamber, F, arranged below such, and in other respects asshown in Fig. 2. The pipe D is to lead from a steam radiator orgenerator, and is to supply the disseminator or foraminous vessel A withsteam, which, owing therefrom through the jacket, will be receivedwithin and discharged from the case B. The jacket is to prevent noise,which, without it, would follow from the passage of the steam throughthe openings of the disseminator. It

also answers one ormore other useful purposes.

Furthermore, the case B and the disseminator and jacket are providedwith a means of getting rid of the condensed steam or the Water thatgathered in and discharged from the jacket would be likely in time tomore or less ll up the case B. One means of accomplishing this result isth chamber F below the disseminator, and extending across the case B, inmanner as shown. The top of this chamber by being heated by the steambefore it may pass into the disseminator, will reconvert into'steam anysurplus Water that may flow from the jacket. Such steam will escape intothe atmosphere through the top of the case B.

Another means of accomplishing such result is shown in Fig. l, it beinga tube, G, extending down from the bottom of the case B, and bent insome part of it in a helix or coil, H, which, when partly filled withwater, serves as a trap to prevent air from passing up the pipe into thevessel B, and also answers one or more other useful purposes. The Waterof condensation escaping from the jacket will be discharged by the eductG.

When the abovedescrihed apparatus is attached to a steam-radiator, steamfrom the latter may be discharged noiselessly into the roorn or theatmosphere therein, in order to meisten it to the extent necessary forhealth or the comfort of persons therein, or for any other purpose.

l sometimes place Within the case B a material for odorizing the steamor vapor. Such material may be in a bag or suitable receptacle, properlyarranged in such case.

I claim- The air moistener, substantially as described, consisting oftheforaminous disseminator A, the surrounding jacket C, the inclosing opencase B, and the induct D, all arranged and applied as set forth, andprovided with means for getting rid of the water of condensationescaping from the jacket, as explained.
